Fuzzy goals and fuzzy constraints can be defined precisely as fuzzy sets in the space of alternatives. A fuzzy decision, then, may be viewed as an intersection of the given goals and constraints. A maximizing decision is defined as a point in the space of alternatives at which the membership function of a fuzzy decision attains its maximum value.
Fuzzy logic is an approach that computes multiple possible truth values by processing through the same single variable. In simple words, fuzzy logic considers a spectrum of possibly useful data to come into a range of accurate conclusions. It bypasses the standard binary Boolean logic of 0 and 1 and proposes an array of options between truth ...

Fuzzy Logic was introduced in 1965 by Lofti A. Zadeh in his research paper "Fuzzy Sets". He is considered as the father of Fuzzy Logic. Fuzzy Logic - Classical Set Theory. A set is an unordered collection of different elements. It can be written explicitly by listing its elements using the set bracket. If the order of the elements is ...
1. INTRODUCTION. Fuzzy set theory and fuzzy logic [1,2] are extensions of classic set theory and logic, which have been largely used in computer science and engineering.The ability of fuzzy inference systems (FISs) [] to deal with uncertainty, represent vague concepts, and connect human language to numerical data, allowed fuzzy logic to be successfully exploited in …
ing fuzzy logic in text summarization is a very re-cent approach in English text summarization (Ya-dav and Meena,2016). (Suanmali et al.,2009) used the fuzzy logic approach to select the sen-tences based on eight features. The system was compared to a baseline summarizer that gener-ates summaries by selecting the first 200 words in
This paper presents a fuzzy logic controller by which a robot can imitate biological behaviors such as avoiding obstacles or following walls. The proposed structure is implemented by integrating multiple ultrasonic sensors into a robot to collect data from a real-world environment. The decisions that govern the robot's behavior and autopilot navigation are …
Fuzzy Name Matching Algorithms. 1) Levenshtein Distance: The Levenshtein distance is a metric used to measure the difference between 2 string sequences. It gives us a measure of the number of single character insertions, deletions or substitutions required to change one string into another.
Fuzzy logic control (FLC) is the most active research area in the application of fuzzy set theory, fuzzy reasoning, and fuzzy logic. The application of FLC extends from industrial process control to biomedical instrumentation and securities. Compared to conventional control techniques, FLC has been best utilized in complex ill-defined problems ...
The parameters of the traditional proportional-integral-derivative (PID) controller are hard to automatically adjust when the controlled object changes, which controls ineffective for time-varying, nonlinear system. Combine the fuzzy control and PID control, and use self-adaptive fuzzy control to achieve self-tuning PID parameters online. Using matlab simulation system, …
Fuzzy control methods and algorithms, including many specialized software and hardware available on the market today, may be classified as one type of intelligent control. This is because fuzzy systems modeling, analysis, and control incorporate a certain amount of human knowledge into its components (fuzzy sets, fuzzy logic, and fuzzy rule base).

The fuzzy logic controller for braking system in train gets activated about 500m from the station. The controller gets its input as speed and distance instantaneously. The numerical values are converted into fuzzy sets by fuzzification technique. Example: For Speed = 70 kmph, distance=200m Speed {very fast, 1} The fuzzy set is, Distance {far, 0 ...

A fuzzy logic controller describes a control protocol by means of if-then rules, such as "if temperature is low open heating valve slightly". The ambiguity (uncertainty) in the definition of the linguistic terms (e.g., low temperature) is represented by using fuzzy sets, which are sets with overlapping boundaries, see Fig. Figure 1.In the fuzzy set framework, a …
